Question

what is ionisation energy or ionisation enthalpy??

Answer 1

Hey!

Answer..

Ionisation potential, also known as ionization enthalpy or ionization energy, is the amount of energy that must be supplied to a gaseous atom/molecule to remove a valence electron from it.

Hope it helps uhh!!

Answer 2

HLO MATE HERE IS UR ANSWER

❤. IONISATION POTENTIAL ❤

⭐. The minimum energy required to remove an electron from the outer most valence shell from an isolated, neutral ,gaseous atom is called ionisation energy.

❤. GROUPS ❤

⭐In groups , From top to bottom the ionisation potential value decrease.

❤. REASON ❤

⭐. In a group , the atomic size increases.

⭐. Hence , the effective nuclear attraction on outer electrons decreases.

⭐. Thus ionisation potential value decreases from top to bottom in a group.

❤. PERIODS ❤

⭐. In a period ,from left to right , the ionisation potential value increases.

❤. REASON ❤

⭐. In a period , the atomic size decreases.

⭐. Hence , the effective nuclear attraction on outer electrons increases.

⭐. Thus ionisation potential value increases from left to right in a period
